Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing device such as a typewriter or word processor.

[0002]

2. Description of the Related Art A general document editing apparatus has a memory area for storing character data for outputting each character.
In the memory, the character data of each character is expressed in a 16 × 16 dot matrix in a dot pattern, for example, and all have the same occupied memory amount, for example, 32 bytes. In addition, each of the character data includes an effective dot row portion that includes at least one dot to be printed (hereinafter referred to as on dot) in one row, and a blank space that does not include any on dot in one row. It is composed of a row part. Then, the fixed-length character data (hereinafter, referred to as dot font) is arranged and stored in a memory in the order of character codes. Further, the head address of the dot font "A" is stored as the reference address of the memory area, and 32 bytes are stored as the occupied memory amount per character.

When a conventional document editing apparatus outputs a character, it is first determined what number character code of the character to be output is from the character code "A". An address obtained by advancing the value from the reference address by 32 bytes of the occupied memory amount becomes the head address of the storage area of the dot font corresponding to the character. A 32-byte dot font was sequentially read from there, and a dot pattern of 16 × 16 dots was output with the blank row portion included.

However, it is inefficient to occupy the memory area in such a manner as to include the blank column portion. for that reason,
In order to reduce the capacity of the memory area that is wastefully used, as in the character pattern generator described in Japanese Patent Publication No. 55-1613, the character string for output does not have a blank column part internally, and effective dot There was also a document editing device in which a dot font composed only of columns was stored in memory.

[0005]

The conventional document editing apparatus has a function of outputting a document stored therein by selecting various line spacing and character spacing.

[0006] By the way, there are cases where it is desired to output with no gap between lines or characters in the document to be output due to the layout. When such editing is attempted by a conventional document editing apparatus, for example, in the former case, when it is desired to close the gap 71 between the character "I" and the character "P" at the time of output as shown in FIG. When the gap 70 between the font 75 and the dot font 76 is set to zero, the blank row portions 72 and 73 existing inside each dot font exist, so that the character gap 71 cannot be completely eliminated.

In the latter case, since the dot font originally does not include a blank line portion, if the gap 80 between the dot font 83 and the dot font 84 is set to zero as shown in FIG. It was possible to However, in the memory that stores the dot font of each character, the width of the dot font occupied by each character is different, so the start address information of the storage area where the dot font is stored for each character data and that dot It was necessary to have a table that stores the size of the font data in association with the character code. Then, when the command to output the character is received, the dot font data amount and the head address information of the character are selected from the table. The address area is designated by this address information, and the dot font is read by sequentially advancing the address by the amount of dot font data of the character.

That is, in the latter character pattern generator, there is a disadvantage that a special correspondence table is prepared, which consumes a large amount of memory, and the reading process is different for each character, so that the processing program becomes complicated.

The present invention has been made in order to solve the above-mentioned problems, and has a fixed-length dot font for simple access to character data, while maintaining the spacing between characters in an output character string. It is an object of the present invention to provide a document editing device that can be set to zero.

[0010]

In order to achieve this object, a document editing apparatus of the present invention stores an input means for inputting a character string and character data composed of a fixed length dot pattern. When the fixed length character data corresponding to each character of the character string input by the input unit is read from the storage unit, the storing unit stores the character data in the arrangement direction of the character strings. Judgment means for judging whether or not the vertically aligned dot row is a blank portion, data reading control means for reading the character data excluding the dot row judged by the judging means as a blank portion, and the data reading The output means outputs the character data so that the intervals between the characters read by the means become a predetermined character interval.

[0011]

In the document editing apparatus of the present invention having the above structure, when the fixed length character data corresponding to each character of the character string input by the input means is read from the storage means, the determination means In the character data, it is determined whether or not the dot row arranged vertically with respect to the arrangement direction of the character string is a blank portion.

Then, the data read control means reads only the effective dot row excluding the dot row judged to be the blank portion.

Each character consisting of only the effective dot row read by the data reading means is output by the output means so that the respective intervals become a predetermined character interval.

The document editing unit mainly includes the editing control device 15, the keyboard 10 via the input control device 11, the display device 12 via the display control device 13, and the output device 14.
And a dot font storage memory 17 and a RAM 18 are connected via the dot font read control device 16.

The input control device 11 converts the input from the keyboard 10 into a code and sends it to the edit control device 15.

The RAM 18 has a pointer Po, a memory for storing a start address A0, a read address Ar, and a final address Af, and a document storage memory 19.
The document storage memory 19 is a memory for storing a character code of a character input from the keyboard 10.

The dot font storage memory 17 stores all the dot fonts that form a character output pattern. Further, it is a memory that stores the leading address of the dot font "A" as the reference address of the storage area that stores them and stores 32 bytes as the occupied data amount per character.

The dot font read control device 16 is
First, from the character code stored in the document storage memory 19, the head address A0 where the dot font of the character is stored is calculated. Then, for the dot font starting from the calculated address A0, only the effective dot row portion is extracted without reading the blank row portion, and the edit control device 15 is sequentially operated.
Send to.

The edit control device 15 stores the input character at a predetermined position in the document storage memory 19, controls the display of the input character, and reads the dot font according to the character string stored in the document storage memory 19. The dot font is read from the dot font storage memory 17 via 16 and the dot font is sent to the output device 14.

The display control device 13 outputs input confirmation character data and the like to the display device 12 in accordance with a command received from the editing control device 15. The output device 14 is the editing control device 15
The plate making operation is performed according to the data sent from.

Next, with reference to FIG. 3 to FIG. 6, a description will be given of the processing for preventing the reading of the blank space inside the dot font in the document editing unit of this embodiment. As an example of printing, as shown in FIG. 3, consider a case where three characters “V”, “I”, and “P” are arranged with one dot left between them. First, the outline thereof will be described according to the flowchart of FIG.

When the character output process starts, it is first recognized that the input buffer contains three characters "V", "I" and "P" (step S51; Yes), and the pointer Po of the input buffer is initialized. (Step S52). First, only the effective dot row of the first character "V" is read and output (step S53), and since there are still two characters remaining (step S54; No), a 1-dot space is output (step S55), and the input buffer The pointer Po of is incremented (step S56). Next, only the effective dot row of the second character "I" is read and output (step S5
3), because one character still remains (step S54; N
o) Output a 1-dot space (step S55),
The pointer Po of the input buffer is incremented (step S56). Finally, only the effective dot row of the third character "P" is read and output (step S53), and the operation is completed when all three characters are output (step S53).
54; Yes).

Of the above processes, as a typical example, the details of the process (step S53 in FIG. 5) of reading only the effective dot row without reading the inner space of the dot font (16 × 16 dots) for “I”. Will be described below.

In the flowchart of FIG. 6, it is first determined from the character code how many characters "I" is separated from "A". Then, the value (+8 in this case) is multiplied by 32 bytes, which is the occupied memory amount, and added to the start address of "A" to calculate the start address A0 of "I" (step S601). Next, in order to recognize the blank column part at the rear of the dot font "I" first, the start address A
The address 30 is added to 0 to form the read address Ar (step S602), and 2 bytes are read from the address indicated by the read address Ar (step S603). This corresponds to reading the data 40 in the 16th column in FIG. Both of the 2-byte data 40 are zero (step S604; Yes) and have not reached the data 42 in the first column (step S60).
5; No) The read address Ar is reduced by 2 addresses (step S606), and the 15th column in the next FIG. 4 is read (step S603). By repeating this process, the data 41 (the 11th column) in the non-zero column is found (step S60).
4; No) Read address at this time and final address A
It is stored as f (step S607).

Next, the read address Ar is returned to the head address A0 (step S608), and 2 bytes are read (step S609). This corresponds to reading the data 42 in the first column in FIG. The 2-byte data 42 are both zero (step S610; Ye
s) and the read address Ar has not reached the final address Af yet (step S612; N).
o) The read address Ar is increased by 2 addresses (step S613), and the second column in FIG. 4 is read out (step S6).
09). Repeating this process, the data 4 in the non-zero column
3 (7th row) is found (step S610; No).
Here, the data 43 in the seventh column is sent to the output means (step S611). The data from the seventh column to the eleventh column is sent to the output means, and it is recognized that the read address Ar has reached the final address Af (step S612; Y).
es) The process ends.

As is clear from the above description, in the stamp apparatus of this embodiment, when reading the dot font from the storage means, only the effective dot row is read without reading the blank portion existing inside the dot font. A document editing unit for reading out is provided. As a result, it is possible to reduce the spacing between the characters in the output character string to zero while having a fixed-length dot font. Then, the dot font is fixed length and is arranged in an orderly manner.
Since it is stored in, the access to the font data can be easily processed without preparing a table for associating the head address in which the dot font is stored with each character. Further, since it is not necessary to store the width of the effective dot portion to be read for each character, it is possible to save the memory.

The present invention is not limited to the above-mentioned embodiment. For example, the embodiment of the present invention exemplifies horizontal character filling. However, vertical character filling in Japanese display is possible. Needless to say. by the time,
The dot font of the character is extracted line by line, and only the effective dot lines are read out.

[0031]

As is clear from the above description, in the stamp device of the present invention, the fixed-length dot font from the storage means is stored so that the character spacing to be output can be reduced to zero. At the time of reading, since the character data read control means for reading only the effective dot row without reading the blank portion existing inside the dot font is provided, while having a fixed length dot font,
The space between characters in the output string can be zero. Further, since the dot font has a fixed length, the process related to data access is simplified.
